Request: git stash create --include-untracked

Hello,

`git stash create` does not accepts the same options that `git stash 
save` accepts.

It would be handy to have `git stash create` accept 
`-u`/`--include-untracked` and `-a`/`--all`. This would allow a very 
simple "freeze-the-world-I-have-to-leave emergency backup" command such as

     git push -f origin $(git stash create 
-u):refs/heads/emergency/$USER-$(date +%s)
